Question

An earthquake affected people living within 90 miles of its epicenter. The population density for this region is 125 people per square mile. About how many people live in the region affected by the earthquake?

Answer 1

11,250

Explanation:

Population density = Number of people / land area

Population density = 125 people per square mile

Number of people = x

Land area = 90 miles

Population density = Number of people / land area

125 = x / 90

Cross product

x = 125 * 90

x = 11,250

About 11,250 people live in the region affected by the earthquake
